History of Innovation and Quality
advancements were
made for one unit to heat
100,000 Sq. Ft. (Current
Air-Rotation Technology
can heat/ cool 150,000
Sq ft.
Johnson Heater
Corporation was
established in
Boston, MA.
Johnson patents the first
Air-Rotation® heating
and ventilating design
applicable to large open
space facilities
Johnson develops indirect and direct-fired
makeup air HVAC offerings.
Johnson/MarCraft launches Arizon Structures
division. Arizon Companies is created with all
three divisions underneath.
Johnson Heater
Corporation purchased
by Ron Scharf and
moved to St. Louis.
Johnson Merges with
MarCraft Custom HVAC
Solutions. Johnson
introduces cooling in its
Air-Rotation® Systems
named to the
INC. 500 list
for the 6th
straight year.
How It Works
At the same time, the unit will “draw” the same amount of air through the return
air section
The continuous process of discharging air up high and returning air from floor
level is what we call the Air-Rotation® effect
Air-Rotation® Systems can routinely circulate conditioned air up to 350 feet
radius for heating and 250 feet radius for cooling units
Typical Johnson Air-Rotation Applications
Manufacturing and Industrial Facilities
Warehouses, Distribution Centers, and Retail
Product Sensitive Storage
Hospital & University Equipment Rooms
Plastic Injection Molding Facilities
Pharmaceutical Storage
Exhibition Centers
Aircraft Hangars
Sports Complexes, Athletic Facilities &
Johnson Air-Rotation Effect
Easy Access for Maintenance
All piping on Johnson Air-Rotation
Systems is easily accessible
outside of the Air-Rotation
The interior of the Air-Rotation
Systems piping, drain pan, coils,
fans, belts, motors and bearings
are easily accessible through a
side-access door.

Johnson Air-Rotation System Features
Fewer Johnson Systems per area –
One system can condition 150,000 Sq. Ft.+
Simplifies gas piping
Fewer electrical power connections
Reduces roof loading-less structural steel
Lower fan motor horsepower reduces wire size
Reduces misc. steel-roof openings framing
Eliminates supply and return air duct work
No roof curbs – less roof openings, hence
minimizing potential leaks
Lower start-up and commissioning costs
Smaller rigging equipment required to set
Lowest Installation Costs
Johnson Air-Rotation Systems have the lowest costs associated with installation in the industry. The total cost
of installation for a Johnson Air-Rotation System is a fraction of the cost to other HVAC systems.
1. No Additional Rooftop Support
2. No Ductwork
3. Fewer Utility Hook-ups
4. No Rooftop Penetrations
5. Installation Time Savings
6. Outdoor or Indoor Mounted
Return on Investment/ Cost Savings
Johnson Air-Rotation Systems Provide Significant Cost Savings Vs. Traditional HVAC Options, Often Resulting
In A Return on Investment For The Customer In A Matter of Years.
1. Utility Savings 30-70%
2. Installation Cost Savings
3. Lower Horse Power
4. Reduced Maintenance
5. Longer Product Life
6. Portability
7. Engineering Support

Compared to other HVAC equipment Johnson Air-Rotation® Systems consume up to 70% less fuel
Less fuel and electric consumption = Huge saving to the customer
Case Study: Manufacturing
Customer Saves $3.5 Million with Johnson Air-Rotation System
Customer: A Major Aircraft Manufacturer
Location: Amarillo, Texas
Building Square Feet: 250,000
System Style: Outdoor, Heating and Cooling
System Size and Qty: 6 Johnson Air-Rotation Systems, for
redundancy purposes required by client
Savings: $3.5 million in savings as a result of less utility
